Laravel Multiple Row Processor is a package for Laravel which is used to manage multiple record processing at database level through CSV files. This makes applications with multiple uploads through CSV, XML, JSON and Flat Text File much easier to maintain.

Installation

Run the following command from you terminal:

composer require "Aderemi/Multiple-Rows-Processor: ^1.0.0"

or add this to require section in your composer.json file:

"Aderemi/Multiple-Rows-Processor: ^1.0.0"

then run composer update

Usage

First, create your Sheet class. Note that your sheet class MUST extend MultipleRows\Contract\MultipleRows and implement four methods rule(string $method, array $data), getUniqueIDField(), processor() and model() And you must define 5 constants which are the headers of your sheets processes

<?php
namespace MultipleRows\Tests;


use MultipleRows\Contract\MultipleRows;

class TestSheet extends MultipleRows
{
    const CREATE_HEADER = ['unique_test_id', 'name', 'status'];
    const UPDATE_HEADER = ['unique_test_id'];
    const DELETE_HEADER = ['unique_test_id', 'name'];
    const STATUS_CHANGE_HEADER = ['unique_test_id'];
    const UNIQUE_FIELDS = ['unique_test_id', 'name'];

    /**
     * @param string $method
     * @param array $data
     * @return array
     */
    protected function rules(string $method, array $data): array
    {
        switch($method){
            case "POST":
                return [
                    'unique_test_id' => "required|unique:" . TestModel::getTableName(),
                ];
            case "PUT" :
                return [
                    'unique_test_id' => "required|exists:" . TestModel::getTableName(),
                ];
        }
    }

    /**
     * @return string
     */
    public function getUniqueIDField(): string
    {
        return 'unique_test_id';
    }

    /**
     * @return string
     */
    protected function model()
    {
        return new TestModel();
    }

    /**
     * @return string
     */
    protected function processor()
    {
        return new TestProcessor();
    }
}
?>
php```
Create the process which will extend MultipleRows\Behaviour\Processor

```php
<?php
use MultipleRows\Behaviour\Processor;

class TestProcessor extends Processor
{

}
?>

php```
